Specification of Letters Iatent.

Application filed April 3, 1909. Serial No. 487,765.

To all whom it may concern:

Be it known that I, BERTJL VON PHILP, a citizen of the United States,and a resident of the borough of Brooklyn, county of Kings, city andState of New York, have invented certain new and useful Improvements inInking Devices, of which the following is a specification, accompaniedby drawings.

This invention relates to improvements in printing presses, and has forits object to keep the inking rollers against the face of the type andprevent them from jumping on the chase when the inking rollers aretraveling at high speed.

To these ends the invention consists of the inking device substantiallyas hereinafter fully described and claimed in this specification andshown in the accompanying drawings, in which- Figure 1 is a sideelevation of the device; Fig. 2 is a front elevation of Fig. 1 lookingin the direction of the arrow 2; Fig. 3 is a transverse detail sectionalview on the line 33 of Fig. 2, looking in the direction of the arrowswith the inking rollers in their lowermost position; Fig. 4 is anenlarged detail side elevation of a portion of the device partly insection with the inking rollers in a slightly different position fromthat shown in Fig. 1; Fig. 5 is a front elevation of Fig. 4:; Fig. 6 isa partial plan view partly in section of the device with the inkingplate removed and the operative connections for the inking rollersrevolved to the lowermost position.

Referring to the drawings, A represents the bed of the press and B theframe upon platen C and from which is supported the vertically movableform carrier D. The form carrier comprises the arms E pivoted on thestuds F carried by the bolts G. The outer ends of the arms E are pivotedto connecting rods H which in turn are connected to the cranks J oncrank disks K, and any suitable means may be provided for driving thecrank disks and thus vertically reciprocating the arms E. Preferablyforming part of the arms E is a casting L havin reduced portions andaffording means or supporting the semicircular inking plate P and theoperative connections for rotating the inking roller carriages. Theinking rollers Q are preferably arranged in pairs on the carriages R andmeans are provided for rotating the carriages and rollers bodily aboutthe form carrier, while keeping the rollers tight against the type intheir chase S as shown in Fig. 3.

Split gears T are mounted on the re duced portions 0 on the ends of thecasting L and on these gears are mounted the split sleeves U carryingthe arms a and 7) upon which are pivoted at 0 and d the bell cranks Vand W. The outer ends of these bell cranks are provided with boxes 6through which pass the rods f pivoted at g to the inking rollercarriages R. The compression springs 71, are arranged in the boxes 0 andare compressed between the upper ends of the boxes and adjusting nutsand washers j and 70, so that the springs h are adapted to maintain theinking rollers in contact with the inking plate. The inner ends of thebell cranks V and W are provided with the rollers 0 which are adapted tofollow the surfaces of the cams p suitably secured against the inside ofthe arms E as by means of the bolts 9. The outer arms of the bellcranksare sufficiently bent or curved as shown in the drawings to bring thepivotal connections of the carriages R in line with each other, and theinner ends of the bell cranks are sufficiently ofiset to bring therollers 0 in line, so that they will travel over the surfaces of thecams 70. These cams p are so shaped and provided with a high portion ofsuch design that as the gear T and with it the arms a and b and bellcranks are revolved, the inner ends of the bell cranks will be forcedoutwardly when the inking rollers are traveling across the type, thusforcing the inking rollers inwardly against the type and making evencontact between the rollers and the type. As the inking rollers rise onthe inkin plate to their uppermost position, the ro lers or followers 0leave the cam surfaces, and the inking rollers follow the surface of theinking plate. The arms a and Z) are preferably provided with stops 1"and the outer arms of the bell cranks are provided with stops 8, so thatthe outward movement of the bell cranks is limited by the stops 1'. Whenthe stops 8 and 1" are in contact the inking rollers bear tightlyagainst the inking plate and adjustment of the pressure is provided bymeans of the springs h. As the inking rollers pass over the type, thesprings it allow for inequalities in the cam and provide elasticity inthe rollers.

In order to actuate the inking rollers and revolve the gears T, anysuitable means may be provided, but in this instance pinions u areprovided on the counter shaft 01 meshing with the gears T and a gear toinside the casting L on counter shaft '0 meshes with the gear 00 on thecentral shaft Y which extends through one of the trunnions of the formcarrier and is provided with a bevel gear 2. Bevel gear 2 on the outsideof the form carrier meshes with bevel gear 2 on the inclined shaft 8which in turn is provided with a bevel gear 4 meshing with the bevelgear 5 on the stud F. Any suitable means may be provided for driving thebevel gear 5 and motion is transmitted by the train of mechanismdescribed, to the gears T, whereby the arms a and b are revolved.

Great difliculty has heretofore been experienced in maintaining theinking rollers tight against the face of the type, as the rollers passover the type, and this is especially true in high speed presses wherethe inking rollers are revolved at high speed. If a spring alone isdepended upon to maintain tension on the inking rollers, the spring mustbe very strong to withstand the centrifugal force tending to extend thespring. Said spring must also be of considerable length, which makes ittoo bulky to be practical.

According to this invention positive means are provided for controllingthe inward and outward movements of the inking rollers, so that they arecaused to bear exactly and evenly both on the inking plate and on thetype in their chase.

I do not herein claim anything disclosed and claimed in my co-pendingapplication Serial No. 469,919, filed December 30,- 1908, forimprovements in continuous printing presses.

I claim and desire to obtain by Letters Patent the following:

1. In a printing press, the combination with a form carrier having aninking plate, of inking rollers adapted to be revolved about the formcarrier, carriages for the rollers, revoluble arms extending adjacentthe carriages, bell crank levers pivoted to said arms and to thecarriages and cams cooperating with the inner ends of said levers todraw the inking rollers inwardly against the type as said rollers passover the chase.

2. In a printing press, the combination with a form carrier havin aninking plate, of inking rollers adapted to be revolved about the formcarrier, carriages for the rollers, revoluble arms extending adjacentthe carriages, bell crank levers pivoted to said arms and to thecarriages and means cooperating with the inner ends of said levers todraw the inking rollers inwardly against the type as said rollers passover the chase.

3. In a printing press, the combination with a form carrier having aninking plate, of inking rollers adapted to be revolved about the formcarrier, carriages for the rollers, revoluble arms extending adjacentthe carriages, levers pivoted to said arms, said levers being adjustablypivoted to said carriages, and cams cooperating with the inner ends ofsaid levers for drawing the rollers against the type as the rollers passover the chase.

4. In a printing press, the combination with a form carrier having aninking plate, of inking rollers adapted to be revolved about the formcarrier, carriages for the rollers, revoluble arms extending adjacentthe carriages, levers pivoted to said arms, said levers being adjustablypivoted to said carriages, and means cooperating with the inner ends ofsaid levers for drawing the rollers against the type as the rollers passover the chase.

(S. In a printing press, the combination with a form carrier having aninking plate, of inking rollers adapted to be revolved about the fomcarrier, carriages for the rollers, revoluble arms extending adjacentthe carriages, levers pivoted to said arms, said levers being adjustablypivoted to said carriages, cams cooperating with the inner ends of saidlevers for drawing the rollers against the type as the rollers pass overthe chase, and stops on the arms for limiting the outward movement ofthe levers and rollers.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses; April 2, 1909.
